Chemistry Research Guide

ChemSpider is a free chemical structure database providing fast text and structure search access to over 100 million structures from hundreds of data sources.

Online version of the classic and well-known reference originally published from 1926 - 1930 for the National Research Council. It contains an enormous amount of critical data on inorganic and organic compounds, and pure substances. Featuring physical, thermodynamic, mechanical, and other key properties, it is a major reference source used by those involved in chemistry, physics, and engineering.

Originally published by Smithsonian Institution Press, this classic reference source comprises 901 tables of general interest to scientists and engineers, and of particular interest to those involved with physics in its larger sense. All entries in the index are hyperlinked to their page numbers.

This reference contains a table of values with a list of substances accompanied by thermochemical data. The data collected includes 5840 values of heats of formation; and 350 values of heats of transition, fusion, vaporization, and reaction. All entries in the index are hyperlinked to their page numbers.
